Hierarchical databases

Hierarchical databases

A hierarchical database is a way to organize information like a tree . Imagine a family tree, where each person is connected to their parents and children . In a hierarchical database, information is stored in records, and these records are connected in a parent-child relationship . Each child record has only one parent, but a parent record can have many children . This creates a clear structure for finding information .

 

This type of database was created in the 1960s, with IBM making one of the first ones . It was a good way to store and find information quickly . To find something, you start at the top, called the root, and go down the branches until you find what you need . It's like following a path down the tree .
